Pro Clima Roflex Grommets
Roflex grommets are heat resistant EPDM rubber seals for airtight sealing around circular pipes and ducting.
Made to Order
Roflex grommets are heat resistant EPDM rubber seals for airtight sealing around circular pipes and ducting. For 15-30mm diameter pipes, Roflex is available as a single pipe grommet with self-adhesive backing or a multiple pipe grommet that needs to be taped. For pipes over 30mm and up to 320mm diameter, Roflex can seal one pipe per grommet and is sealed with Tescon Vana airtight tape. Tescon Vana is a tape that has been tested and proved to remain airtight for 100 years. Roflex of 30mm and larger and sold in pack sizes of 10 or 15 grommets do not come with tape.
- Roflex grommets should be installed before pipe work is completed. At least one end of the pipe must be accessible so the grommet can be slid over the end. Grommets must never be cut or split to fit around fully completed pipe work.
- It is important that the maximum pipe diameter for a grommet is not exceeded; overstretching the EPDM rubber will compromise the integrity of the material and lead to air leakage.
- For the single pipe grommets, slide the grommet into position up to the airtight barrier. Then use the supplied Tescon Vana Airtight Tape to seal around the grommet.
- For Roflex 20 Multi, you must first decide how many holes you need and where on the rubber grommet you need them. Place the rubber grommet onto a smooth hard surface (e.g. planed timber, MDF, plywood or plastic cutting mat).
- Align the paper template centrally over the top of the grommet. Put the metal punch, with the sharpened end touching the grommet, over one of the circles printed on the template and strike firmly with a hammer to cut a precise hole in the rubber.
- Repeat as needed. If you cut more holes than you need, you can tape over the excess holes with Tescon Vana.
- After cutting the holes, slide the grommet over all pipes/cables and position up against the airtight barrier. Use the Tescon Vana airtight tape supplied in the box to seal the grommet to the surrounding area then press firmly.
Suitable For
- Pro Clima Roflex heat-resistant EPDM rubber grommets can be used internally or externally on walls, ceilings, floors and roofs (of more than 15° of pitch). It is compatible with circular pipes, flues and ducts where you have access to one end and the temperature will not exceed 150°C. Access to a free end is required so the grommet can be slid onto the pipe or duct like a tight-fitting collar. Roflex can be used with pipe diameters of 15-320mm.
- The smallest size, Roflex 20, has an integrated Tescon Vana self adhesive backing (patch). All other sizes will require Tescon Vana airtight tape for sealing the grommet to an airtight barrier. Roflex sold in pack sizes of 10 or 15 grommets do not come with tape so please purchase this separately. Tescon Vana's waterproof solid acrylic adhesive will permanently stick to any airtight or windtight membrane, wood-based panel or board, smooth planed or painted timber, metal or plastic.
- Easy professional or DIY solution
- Does not stick to the pipe
- Highly adaptable
- Easily seal around all common pipe and duct sizes
- No expanding foam required
- Stretchy EPDM rubber allows the user to easily seal around pipes and ducts with confidence in achieving a permanent airtight seal.
- The grommet allows for pipes and ducts to be re-positioned after installation without affecting the airtight seal.
- Highly versatile with multiple sizes available to seal any pipe/duct between 20-320mm diameter.
- The self-adhesive backed Roflex 20 EPDM grommet means that common 15-30mm pipework can be sealed extremely quickly.
- Seal up to nine 15-30mm pipes with one Roflex 20 Multi.
- Avoid the use of messy, less effective and non-permanent expanding foams.
